Refractive errors are measured in diopter (D), and myopia is specified with a negative sign. Severity of myopia is categorized into 3 levels. 1) Mild (0 to -1.5D), 2) moderate (-1.5D to -6.0D) and 3) and severe myopia (-6.0D or above). Pathogenic myopia develops, when this condition advances to -8.0 D and above. Visual disorders - moderate retina disorders, cataract, and glaucoma - may be seen in patients with moderate and severe myopia. At birth, most infants are hyperopic but this condition lowers when they grow up and by the age 5-8, eyes must be emmetropic (normal and without any refractive error) (2).
